ok, so let's add latest saga to this thread / same issue as I hope it helps someone else who may run in to this problem. Dec 2019 update. Last summer (2019) I did buy a new ignition switch off ebay, of course after it arrived the tractor stopped acting up so the spare sat in garage until about a month ago when once again no start issue reappeared... I swapped out the ignition switch (easy peasy BTW - too easy I thought !) then realized the new ignition switch was a single sided key (not double sided which came with tractor) so off to dealer, got single sided key, insert and Varoom, she starts right up! Viola ! It WAS the ignition switch !! Then a week or two goes by and I go to start and same issue reappears, click, no start, some fiddling with foot on brake, jostle around in seat and making sure she's in Neutral (trying both neutral positions, and she finally starts, (I think I even sprayed a little wd 40 in key slot for good luck)... then wait a week til next tractor chore and she no start again.... jumping/jostling in seat, tapping brake pedal, making sure in neutral, been on trickle charger so she's got voltage.... after 100+ turns of ignition I decide to pop out the seat and strip the wires to connect the Seat Disconnect (this was an issue in 2017 when the Seat Cut Off wire severed in half after some bouncing around ripping tree stumps out - the seat was removed by dealer and the 'seat sensor & wire' were replaced and reinstalled by dealer).... SO - I cut the seat sensor wire, strip and twist together , bolt seat back down (4 easy bolts) and VIOLA she starts right up ! Of course now I have to bring the seat to dealer to see what recourse I have there....but for anyone out there troubleshooting a no start issue on a 2017 NX6010 you might wanna try..... good luck everyone and thank you all for the support I find in here. Merry Christmas Erik
